At the end of this past season with the Oakland Raiders, an aching Rolando McClain gave an assignment to his agent: Find out more about stem cell therapies for injuries, like other athletes are trying.

“I’ve been having two seasons of nagging pain in my knee,” the former University of Alabama standout said.

Not long afterward, McClain was on his way to Gulf Shores. There, radiologist Jason R. Williams performed liposuction on McClain and then injected stem cells from the linebacker’s own fat cells into his knee and into the area of a high ankle sprain.

It's starting to look like McClain really has played his last down as a Raider. Jay Glazer said:

"Players there, they're telling me this has been an ongoing problem with Rolando McClain," Glazer reported Sunday. "The tipping point was last week. Somebody asked him, 'Do you even care?' He said, 'I've got four million reasons not to care.'"
